Fact Sheet | May 1, 2019 Summary Characteristics of the Notes Summary Risk Considerations • Commissions—Barclays Capital Inc. will receive commissions from the Issuer of up to 1.00% of the principal amount of the notes, or up to $10.00 per $1,000 principal amount. Please see the accompanying Pricing Supplement for additional information about selling concessions, commissions and fees. • Estimated Value Lower Than Issue Price—Our estimated value of the notes on the Initial Valuation Date is expected to be between $950.00 and $972.70 per note. Please see “Additional Information Regarding Our Estimated Value Of The Notes” in the accompanying Pricing Supplement for more information. •Your Return on the Notes Is Limited to the Payment at Maturity--You will not receive any interest or coupon payments on the notes or any other payments aside from the Payment at Maturity. If the Final Level is less than or equal to the Initial Level, your Payment at Maturity will be limited to the principal amount of your notes and you not earn any positive return. The return at maturity of the principal amount of your notes plus any amount in excess thereof may not compensate you for any loss in value due to inflation and other factors relating to the value of money over time. Any payment on the notes, including the repayment of principal, is subject to the credit risk of Barclays Bank PLC. • Credit of Issuer—The notes are senior unsecured debt obligations of the Issuer and are not, either directly or indirectly, an obligation of any third party. In the event the Issuer were to default on its obligations, you may not receive any amounts owed to you, including any payment at maturity under the terms of the notes. • U.K. Bail-In Power—Each holder of notes acknowledges, accepts, and agrees to be bound by, and consents to the exercise of, any U.K. Bail-in Power by the relevant U.K. resolution authority, which may be exercised so as to result in you losing all or a part of the value of your investment in the notes or receiving a different security from the notes that is worth significantly less than the notes. Please see “Consent to U.K. Bail-In Power” in the accompanying Pricing Supplement for more information. • Historical Performance—The historical performance of the Index is not an indication of the future performance of the Index over the term of the notes. • Conflict of Interest—In connection with our normal business activities and in connection with hedging our obligations under the notes, we and our affiliates play a variety of roles in connection with the notes, including acting as calculation agent and as a market-maker for the notes. In each of these roles, our and our affiliates’ economic interests may be adverse to your interests as an investor in the notes. • Payment at Maturity Is Based Solely on the Closing Level on the Final Valuation Date—The Final Level (and resulting Index Return) will be based solely on the Closing Level of the Index on the Final Valuation Date (as compared to the Initial Level). Therefore, if the level of the Index drops on or before the Final Valuation Date, then the Payment at Maturity you may receive on the notes may be significantly less than it would have been had such payment been linked to the level(s) of the Index at any time prior to such drop. • Lack of Liquidity—The notes will not be listed on any securities exchange. There may be no secondary market for the notes or, if there is a secondary market, there may be insufficient liquidity to allow you to sell the notes easily. • Tax Treatment—Significant aspects of the tax treatment of the notes are uncertain. You should consult your tax advisor about your tax situation. In addition to the summary risks and characteristics of the notes discussed under the headings above, you should carefully consider the risks discussed under the heading “Selected Risk Considerations” in the accompanying Pricing Supplement and under the heading “Risk Factors” in the accompanying prospectus supplement.
